The interviewer wants to know more about your career progression. Additional responsibilities, promotions, and changes in your job title all indicate that you were competent and successful in your role.

This question gives you an opportunity to go more in-depth about how your job has evolved. If nothing has changed much over the past couple of years in your position, focus on what you have learned.

Are you better at managing teams now that you have gone from supervising one to five people? Are you exceptionally good at problem-solving now that you've learned to troubleshoot IT related problems? Talk about how the changes in your job have taught you new skills and helped you develop the ones you already have.
